- controls the frequency of a frequency boost?
- controls the mix of the clean input signal with the effected signal
- controls the amount of fuzz
- controls the output level
The SF-04 cuts the peaks of the original signal. It produces a smooth and plastic sound, which is rich of harmonic components. Due to the use of a unique filter circuit, it is possible to create the typical fuzz effect as well as a whole bunch of other tones.
